Part A

The $52-lb$ block is released from rest on the rough inclined surface for which the

coefficient of kinetic friction is ${}_k=0\mathrm{.}2.$ The block is attached to a spring and the

spring is undeformed at the instant of releasing.

$($Figure $1)$

Determine the maximum amount of stretching of the spring, $s_{\text{m}\text{a}\text{x}},$ once the block is released from rest.

Express your answer to three significant figures with proper units.
